Description

La présente invention se rapporte à appareil électroménager, tel un fer à repasser, comprenant une plaque chauffante alimentée électriquement par un circuit d'alimentation comprenant un thermostat équipé d'un coupe-circuit thermique, et se rapporte plus particulièrement à un appareil dans lequel le coupe-circuit thermique comporte un interrupteur maintenu en position fermée par un organe de transmission en contact avec l'interrupteur et avec un bouchon fusible contenu dans une cavité de la plaque chauffante, et dans lequel l'organe de transmission s'oppose à l'ouverture de l'interrupteur sous l'effet de moyens de rappel.The present invention relates to an appliance, such as an iron, comprising a heating plate electrically powered by a supply circuit comprising a thermostat equipped with a thermal cut-out, and relates more particularly to an apparatus in which the thermal circuit breaker comprises a switch held in closed position by a transmission member in contact with the switch and with a fuse plug contained in a cavity of the heating plate, and wherein the transmission member opposes the opening of the switch under the effect of return means.

Il est connu, de la demande de brevet FR 2 656 952 déposée par la demanderesse, un fer à repasser comportant une plaque chauffante alimentée électriquement par un circuit d'alimentation comprenant un thermostat équipé d'un coupe-circuit thermique. Dans ce document, le coupe-circuit thermique est constitué par un interrupteur maintenu en position fermée par une tige de transmission en contact avec l'interrupteur et avec un bouchon fusible contenu dans une cavité de la plaque chauffante, l'organe de transmission s'opposant à l'ouverture de l'interrupteur sous l'effet ressort de la lame de contact de l'interrupteur.It is known from the patent application FR 2 656 952 filed by the applicant, an iron having a heating plate electrically powered by a supply circuit comprising a thermostat equipped with a thermal cut-out. In this document, the thermal circuit breaker is constituted by a switch held in closed position by a transmission rod in contact with the switch and with a fuse plug contained in a cavity of the heating plate, the transmission member s' opposing the opening of the switch under the spring effect of the contact blade of the switch.

Un tel appareil présente l'avantage de comporter un thermostat intégrant directement un dispositif coupe-circuit, permettant de réduire les opérations de montage et donc le coût de fabrication de l'appareil.Such a device has the advantage of having a thermostat directly integrating a circuit breaker device, to reduce the mounting operations and therefore the cost of manufacturing the device.

Le coupe-circuit ainsi intégré au thermostat améliore grandement la sécurité d'utilisation de l'appareil car il permet d'éviter un échauffement excessif de la semelle chauffante du fer, et donc le risque de provoquer un incendie, en cas de défaillance du thermostat. En effet, lorsque le thermostat ne remplit plus sa fonction de régulation de la température, la température de la semelle augmente jusqu'à atteindre la température de fusion du bouchon fusible contenu dans la cavité de la plaque chauffante. Lorsque cette température est atteinte, la tige de transmission plonge dans la matière en fusion sous l'effet de la pression exercée par l'effet ressort de la lame de contact, ce qui provoque l'ouverture de l'interrupteur.The circuit breaker integrated in the thermostat greatly improves the safety of use of the device because it avoids excessive heating of the heating plate of the iron, and therefore the risk of causing a fire, in case of failure of the thermostat . In fact, when the thermostat no longer fulfills its function of regulating the temperature, the temperature of the soleplate increases until it reaches the melting temperature of the fusible plug contained in the cavity of the heating plate. When this temperature is the transmission rod is immersed in the melt under the effect of the pressure exerted by the spring effect of the contact blade, which causes the opening of the switch.

Toutefois, la demanderesse s'est rendu compte que, dans de rares cas, le coupe-circuit pouvait être rendu inopérant par la présence de bavures dans la cavité qui empêchaient la tige de transmission de plonger dans la cavité malgré la fusion du bouchon. De telles bavures peuvent en effet être générées lors du processus de réalisation de la cavité dans la plaque chauffante.However, the Applicant has realized that, in rare cases, the circuit breaker could be rendered inoperative by the presence of burrs in the cavity which prevented the transmission rod from plunging into the cavity despite the fusion of the plug. Such burrs can indeed be generated during the process of making the cavity in the heating plate.

Aussi, un but de la présente invention est de proposer un appareil électroménager remédiant à ces inconvénients. En particulier, un but de la présente invention consiste à proposer d'un appareil électroménager comprenant un thermostat équipé d'un dispositif coupe-circuit amélioré, garantissant une plus grande sécurité d'utilisation à l'appareil.Also, an object of the present invention is to provide an appliance remedying these disadvantages.

Une lame bimétallique 37 est fixée à la base du corps du thermostat 3, elle est attelée mécaniquement à la lame 6 par une tige isolante 38.The thermostat 3 further comprises a rigid blade 5 integral with the body of the thermostat 1. Each of the blades 5 and 6 has contacts 5a and 6a. A bimetallic blade 37 is fixed to the base of the body of the thermostat 3, it is mechanically coupled to the blade 6 by an insulating rod 38.

Lorsque la température de consigne est atteinte, l'incurvation de la lame bimétallique 37 provoque, de manière connue en soi, le déplacement de l'extrémité 6b de la lame 6, ce qui a pour conséquence de provoquer l'écartement brusque des contacts 5a et 6a portés respectivement par les lames 5 et 6. L'alimentation électrique de la résistance 20 électrique de la semelle 2 est alors coupée.When the set temperature is reached, the bending of the bimetallic blade 37 causes, in a manner known per se, the displacement of the end 6b of the blade 6, which has the consequence of causing the abrupt separation of the contacts 5a. and 6a respectively carried by the blades 5 and 6. The power supply of the electrical resistance of the sole 2 is then cut off.

En agissant sur la vis 36, l'utilisateur peut modifier la position du point d'appui sur la lame souple 4, et par là modifier la température de déclenchement du thermostat 3.By acting on the screw 36, the user can change the position of the fulcrum on the flexible blade 4, and thereby change the trigger temperature of the thermostat 3.

Comme on peut le voir sur la figure 3, la lame 5 rigide comporte également une plage de connexion électrique 5b formant un angle de l'ordre de 45° avec la partie de la lame 5 portant le contact 5a.As can be seen on the figure 3 the rigid blade 5 also has an electrical connection pad 5b forming an angle of the order of 45 ° with the portion of the blade 5 carrying the contact 5a.

Le thermostat 3 intègre également un dispositif coupe-circuit thermique comportant un interrupteur 7 comprenant une lame de contact 71 souple, à effet ressort, en liaison électrique avec la lame 4 souple et une lame de contact 72 rigide munie d'un partie de connexion 72B, la lame de contact 71 souple étant disposée au-dessous de la lame de contact 72 rigide et portant un contact 71A qui vient prendre appui contre un contact 72A de la lame de contact 72 rigide.The thermostat 3 also incorporates a thermal cut-out device comprising a switch 7 comprising a flexible contact blade 71, with spring effect, in electrical connection with the flexible blade 4 and a rigid contact blade 72 provided with a connection portion 72B , the flexible contact blade 71 being disposed below the rigid contact blade 72 and carrying a contact 71A which bears against a contact 72A of the rigid contact blade 72.

Conformément à la figure 4, l'interrupteur 7 est maintenu en position fermée par un organe de transmission 8 reposant verticalement sur un bouchon fusible 22 logé dans une cavité 21 pratiquée dans la plaque chauffante 2, ce bouchon fusible 22 étant réalisé dans un alliage susceptible de fondre à une température de l'ordre de 390°C, à laquelle on souhaite couper l'alimentation électrique de la résistance 20 de la plaque chauffante 2 en cas de défaillance du système de régulation du thermostat 3.In accordance with the figure 4 , the switch 7 is kept in the closed position by a transmission member 8 standing vertically on a fuse plug 22 housed in a cavity 21 formed in the heating plate 2, this fuse plug 22 being made of an alloy capable of melting at a temperature of the order of 390 ° C, at which it is desired to cut off the power supply of the resistor 20 of the heating plate 2 in the event of failure of the regulation system of the thermostat 3.

L'organe de transmission 8 comporte une tige 81 métallique présentant une extrémité inférieure en contact avec le bouchon fusible 22 et comporte une tête 82 en céramique présentant une extrémité supérieure en contact avec la lame de contact 71 souple de l'interrupteur 7, la lame de contact 71 prenant appui sur la tête 82 à la manière d'un ressort pour pousser la tige 81 sur le bouchon fusible 22. Le corps du thermostat 3 comporte une platine inférieure 39 qui s'étend latéralement au-dessus de la cavité 21 et qui comprend un orifice traversé par la tige 81, assurant un guidage transversal de la tige 81 au-dessus du bouchon fusible 22.The transmission member 8 comprises a metal rod 81 having a lower end in contact with the fuse plug 22 and comprises a ceramic head 82 having an upper end in contact with the flexible contact blade 71 of the switch 7, the blade contact member 71 bearing on the head 82 in the manner of a spring to push the rod 81 on the fuse plug 22. The body of the thermostat 3 comprises a bottom plate 39 which extends laterally above the cavity 21 and which includes an orifice crossed by the rod 81, providing transverse guidance of the rod 81 above the fuse plug 22.

Plus particulièrement selon l'invention, l'organe de transmission 8 comporte également un élément fusible 83 qui est avantageusement interposé entre la tête 82 et la tige 81, l'élément fusible 83 étant réalisé dans un alliage susceptible de fondre lorsque la température de la plaque chauffante 2 atteint une température plus élevée que la température de fusion du bouchon fusible 22, par exemple lorsque la température de la plaque chauffante 2 est supérieure à 400°C.More particularly according to the invention, the transmission member 8 also comprises a fuse element 83 which is advantageously interposed between the head 82 and the rod 81, the fuse element 83 being made of an alloy capable of melting when the temperature of the The heating plate 2 reaches a temperature higher than the melting temperature of the fusible plug 22, for example when the temperature of the heating plate 2 is greater than 400 ° C.

A titre d'exemple, compte tenu du gradient thermique s'établissant entre le bouchon fusible 22 et l'élément fusible 83 du fait des pertes thermiques se produisant dans l'organe de transmission 8, l'élément fusible 83 présentera avantageusement une température de fusion inférieure à 300 °C.By way of example, given the thermal gradient established between the fusible plug 22 and the fuse element 83 because of the heat losses occurring in the transmission member 8, the fuse element 83 will advantageously have a temperature of melting below 300 ° C.

De manière préférentielle, l'élément fusible 83 comporte une extrémité inférieure prenant appui sur une extrémité supérieure de la tige 81 et comporte une extrémité supérieure qui est engagée dans une cavité de la tête 82, la tête 82 comportant une jupe périphérique s'étendant autour de l'élément fusible 83.Preferably, the fuse element 83 has a lower end bearing on an upper end of the rod 81 and has an upper end which is engaged in a cavity of the head 82, the head 82 having a peripheral skirt extending around of the fuse element 83.

La jupe périphérique comprend avantageusement une extrémité inférieure munie d'une ouverture centrale 82A dans laquelle vient s'engager l'extrémité supérieure de la tige 81, cette ouverture centrale 82A présentant un diamètre adapté au diamètre de la tige 81 de sorte que la tête 82 peut coulisser sur l'extrémité supérieure de la tige 81 en étant guidée selon l'axe longitudinal de cette dernière lors de la fusion de l'élément fusible 83. La jupe périphérique comprend également deux ouvertures oblongues 82B verticales, visibles également sur la figure 1, disposées en vis-à-vis et dans lesquelles est engagé un axe 84 transversal solidaire de la tige 81, cet axe 84 venant délimiter une course de débattement longitudinal de la tête 82 sur l'extrémité de la tige 81 lors de la fusion de l'élément fusible 83.The peripheral skirt advantageously comprises a lower end provided with a central opening 82A in which is engaged the upper end of the rod 81, this central opening 82A having a diameter adapted to the diameter of the rod 81 so that the head 82 can slide on the upper end of the rod 81 being guided along the longitudinal axis of the latter during the melting of the fuse element 83. The peripheral skirt also comprises two oblong openings 82B vertical, also visible on the figure 1 , disposed opposite and in which is engaged a transverse axis 84 integral with the rod 81, this axis 84 defining a longitudinal travel stroke of the head 82 on the end of the rod 81 during the merger of the fuse element 83.

Dans la position représentée sur la figure 4, les deux lames de contact 71, 72 ferment le circuit d'alimentation électrique de la résistance 20 chauffante et l'alimentation de celle-ci est assurée tant que les contacts 5a et 6a du thermostat sont eux-mêmes en contact.In the position shown on the figure 4 the two contact blades 71, 72 close the electrical supply circuit of the heating resistor 20 and the power supply thereof is ensured as long as the contacts 5a and 6a of the thermostat are themselves in contact.

Le fonctionnement de l'interrupteur coupe-circuit intégré au thermostat 3 va maintenant être décrit en relation avec les figures 5 et 6.The operation of the integrated circuit breaker switch at the thermostat 3 will now be described in connection with the Figures 5 and 6 .

En cas de défaillance du thermostat 3, la température de la plaque chauffante 2 continue de monter rapidement. Dès que cette température atteint le point de fusion de la matière du bouchon fusible 22, celui-ci fond.In the event of a thermostat 3 failure, the temperature of the heating plate 2 continues to rise rapidly. As soon as this temperature reaches the melting point of the material of the fusible plug 22, it melts.

Comme cela est illustré sur la figure 5, la tige 81 de l'organe de transmission plonge alors dans la matière en fusion et descend dans la cavité 21. Du fait de la descente de la tige 81, la lame de contact 71 fléchit vers le bas de part son effet ressort, et son contact 71A s'écarte du contact 72A de l'autre lame de contact 72.As illustrated on the figure 5 , the rod 81 of the transmission member then plunges into the molten material and goes down into the cavity 21. Due to the descent of the rod 81, the contact blade 71 bends downwards from its spring effect, and its contact 71A deviates from the contact 72A of the other contact blade 72.

L'alimentation électrique de la résistance 20 chauffante contenue dans la plaque chauffante 2 est alors coupée.The power supply of the heating resistor contained in the heating plate 2 is then cut off.

Dans le cas où la descente de la tige 81 de l'organe de transmission 8 dans la cavité 21 est rendue impossible, par exemple à cause de la présence d'une bavure en bordure de la cavité 21, l'interrupteur 7 coupe-circuit reste fermé malgré la fusion du bouchon fusible 22.In the case where the descent of the rod 81 of the transmission member 8 in the cavity 21 is made impossible, for example because of the presence of a burr on the edge of the cavity 21, the switch 7 circuit breaker remains closed despite the fusion of the fusible plug 22.

La température de la plaque chauffante 2 continue alors d'augmenter jusqu'à ce que la chaleur transmise au travers de la tige 81 conduise l'élément fusible 83 de l'organe de transmission 8 à atteindre également sa température de fusion.The temperature of the heating plate 2 then continues to increase until the heat transmitted through the rod 81 leads the fuse element 83 of the transmission member 8 to also reach its melting temperature.

Comme cela est illustré sur la figure 6, la fusion du bouchon fusible 22 provoque la descente de la tête 82 le long de la tige 81 sur une course de plusieurs millimètres, de sorte que la longueur de l'organe de transmission 8 se trouve réduite, ce qui provoque la descente de la lame de contact 71 vers le bas, sous l'influence notamment de son effet ressort, et son contact 71a s'écarte du contact 72a de l'autre lame de contact 72.As illustrated on the figure 6 the melting of the fusible plug 22 causes the head 82 to descend down the rod 81 over a course of several millimeters, so that the length of the transmission member 8 is reduced, which causes the descent of the contact blade 71 downwards, in particular under the influence of its spring effect, and its contact 71a deviates from the contact 72a of the other contact blade 72.

L'alimentation électrique de la résistance 20 chauffante contenue dans la plaque chauffante 2 est alors coupée et celle-ci ne risque plus d'être chauffée davantage, éliminant ainsi un risque d'incendie.The power supply of the heating resistor contained in the heating plate 2 is then cut off and it is no longer likely to be heated further, thereby eliminating a risk of fire.

L'appareil ainsi réalisé présente donc l'avantage de procurer une sécurité améliorée grâce à la présence de deux dispositifs fusibles disposés en série qui coopèrent avec le même interrupteur coupe-circuit, la présence du deuxième dispositif fusible permettant de pallier une défaillance d'ouverture de l'interrupteur coupe-circuit suite à un blocage de l'extrémité inférieure de la tige dans la cavité de la plaque chauffante.The apparatus thus produced thus has the advantage of providing improved security thanks to the presence of two fusible devices arranged in series which cooperate with the same circuit breaker switch, the presence of the second fuse device for mitigating a failure opening of the circuit breaker switch following a blockage of the lower end of the rod in the cavity of the heating plate.

De plus, l'intégration du deuxième dispositif fusible dans l'organe de transmission permet de conserver un thermostat équipé d'un coupe-circuit qui reste compact, de construction simple et qui peut être monté en une seule opération sur la plaque chauffante du fer à repasser.In addition, the integration of the second fuse device in the transmission member makes it possible to maintain a thermostat equipped with a circuit breaker which remains compact, of simple construction and which can be mounted in a single operation on the hotplate of the iron to redo.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, l'invention peut s'appliquer à tout appareil électroménager muni d'une plaque chauffante dont la température est régulée au moyen d'un thermostat et pas seulement au domaine des fers à repasser.Thus, the invention can be applied to any household appliance provided with a heating plate whose temperature is regulated by means of a thermostat and not only in the field of irons.
